摘要

提出一种16APSK信号的高速并行载波同步算法。该算法采用递归结构设计环路滤波器与数控振荡器。在Simulink平台上进行仿真，并在800 Msps符号速率的高速条件下，与现有的两种并行载波同步算法进行对比测试。结果表明，在误比特率性能与对比算法相同的同时，该算法捕获带宽提升至对比算法的2倍以上。采用该算法完成解调时，解调损失小于1.5 dB。

Abstract

A high-speed parallel carrier synchronization algorithm for 16APSK signals was proposed. The algorithm utilized a recursive structure to design the loop filter and numerically controlled oscillator. Simulations were conducted on the Simulink platform

and comparative tests were performed with two existing parallel carrier synchronization algorithms under high-speed conditions with a symbol rate of 800 Msps. The results demonstrated that

while maintaining the same bit error rate performance as the comparison algorithms

the capture bandwidth of the proposed algorithm was increased to more than twice that of the comparison algorithms. When using this algorithm for demodulation

the demodulation loss was less than 1.5 dB.
